T LLZZ whont it Wuty concern:

Be it known that we, ADRIAN HALL and J GEN M. HALL, of Greenfield, county of Hancock, and State of Indiana, have invented a certain new and useful Conveying Apparatus and we do herebydeclare that the following is a full, clear, and exact description ing-cable at any time while the conveyingcable is being operated.

These and the other improvements in our present invention will appear from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a perspective view of the operative device in connection with cables and supports to illustrate its use.

Fig. 2 Ba perspective view of the operating device. Fig. 3 is a central section longitudinally through the driving-shaft and associated parts, parts being broken away. Fig. 4

is a plan view of the right-hand side of the (le vice as shown in Fig. 2, parts being broken away and parts of the machine being shown in their idle position. Fig. 5 is a sectional view of the left-hand end of the drivingshaft, parts being broken away. Fig. 6 is a vertical section along the line 6 6 of Fig. 4, parts being broken away and the frame being shown by dotted lines and the altered position of the reversing-pulley and crank being shown in dotted lines. Fig. 7 is a side elevation of the left-hand side of the device as shown in Fig. 2 on a smaller scale and with many parts removed to show the means for holding and releasing the supporting-cable.

In detail the operating mechanism is mounted on a frame having a base 10, rear uprights 11, inclined side braces 12, and a cross-piece 13. About midway of the inclined braces 12 a drum 14is mounted in the bearings 15, on which the supporting-cable 16 is wound, that passes from said drum over forks 17 to a dead man 18. The purpose of this drum is to hold and tighten the cable, for said cable carries the pulley 19 and carrier 20, by which the material-such as coal, cotton, gravel, or the likemay be con Vcyed. The carrier is to be modified to suit the material being transported and the work being done.

The shaft of drum 14 on its outer end car ries a ratchet-wheel 21, that is engaged by a pawl 22 to hold the drum from backward movement. Said pawl is held in place by a spring 23 and is released by a rod 24 and hand-lever 25, that is fulcrumed to the side of the left-hand inclined brace 12 and is held in place by the usual pawl and rack.

The drum 14 is actuated through the gear 27, that is secured thereto and meshes with a loose pinion 28 on the driven shaft 29. Said shaft 29 is driven from some suitable source of power through the pulley 30, and it is put into operative engagement with the pinion 28 by means of a conical clutch. The female member 31 of said clutch forms a part or is secured to the pinion 28. The male member 32 of the clutch is splined on the shaft 29, so as to be movable into and out of engagement with the other member of the clutch by the irregularly formed lever 34, that is fulcrumed at 35 to two brackets or arms 36 and 37, which are fastened to the base-pieces 10. Said lever 34 is actuated by a connecting-rod 38, running to a foot-lever 39, which is fulcrumed at 40 to the rear upright 11 and has the pedal 41 at the forward end for its actuation. When the pedal is depressed, the two members of the clutch are brought into engagement and the drum 14 driven until the supporting-cable is taut and the clutch slips. The pawl 22 will prevent the backward movement of the drum 14, and then the pedal is released, whereupon the spring 42 disengages the members of the clutch, as seen in Fig. 3, the releasing movement of the clutch member 32 being stopped by a block 43.

The carrier 20 is transported along the supporting-cable by cables 50 and 51, secured thereto. The cable 51 is connected with the carrier and extends therefrom over a pulley 52 back to the lower drum 53, which is mounted in suitable bearings on the inclined braces 12. The other cable 50 extends from the carrier over a pulley 54 to an upper drum 55, the shaft 56 of which is mounted in the brackets or arms 57.

The cables 50 and 51 are moved by the alternate action of the drums 53 and 55. The carrier 20 is moved toward the machine by the upper drum and away from the machine by the lower drum. These two drums are operated ultimately from a single source of powerthe shaft 29. On said shaft there is a friction e pulley 60, that is adapted to be moved into engagement with either the pulley 61 or pulley 62. The pulley 61 is on the shaft of the lower drum 53. The pulley 62 is on the spindle 63. It carries a sprocketwheel 64, and through a chain 65 and sprocket wheel 66 the shaft 56 of the upper drum is actuated.

In or." er to move the pulley into engf-gement with either of the pulleys 61 or 62, the

riving sh .ft 29 is mountel mov. bly, is slrown Fig. 3. At the en next to the riving-pulley 30 s i sh ft is mounta in ipulley-be ring 67. At the other en. s i" sh ft is mounted locsfly in n eccentric 68, which in turn is mounte in be ring 69, secure F to the si. le of the right h ,n.l inclined fr. vmebrace 12. The eccentric 68 is actuated by crank 70, connecting-rod 71, and hand-lever 72, that is fulcrumed to a bracket 73.- It is evident, therefore, that by the movement of said hand lever 72 the pulley 60 can be moved into engagement with either pulley 61 or 62, so as to move the load in either direction, or said pulley may be moved into an idle position, as shown in Fig.4.

A pedal-actuated brak-lever 80 is fulcrumed at 81 to the side of the base 10 and carries a shoe 82, adapted to engage the pulley 61 and stop the load in any desired position and hold it there while the brake is held in engagement.

That we claim as our invention, and desire to secure by Letters Patent, is

1. In a conveying apparatus, the combination of a carrier, cables extending from said carrier for moving the same in opposite directions, a pair of drums for operating said cables, pulleys for driving each drum, a friction driving-pulley intermediate said firstmentioned pulleys that is movable into or out of engagement with either or both of said pulleys, a shaft 'on which said driving-pulley is mounted, an eccentric bearing for said shaft, and a lever-actuated means for operating said eccentric-bearing.

2. In a conveying apparatus, a carrier, cables connected with said carrier for moving the same in opposite directions, a pair of drums for drawing said cables so as to cause opposite movement of the carrier, a frame on which said drums are mounted, a pulley mounted in connection with one drumeshaft, a corresponding pulley mounted on the frame, means for transmitting power from said lastmentioned pulley to the other drum, a friction driving pulley between said two mentioned pulleys, a shaft on which said drivingpulley is mounted, an eccentric-bearing for sjiid shaft, and a lever-actuated means for oper ting s il eccentric bearing so as tov 0 use the movement of aid driving-pulley into or out of eng gement with either or both of s i pulleys, subst.v..nti--lly z s set forth.

3. In a conveying apparatus, a stationary supporting cable, a carrier on s id cable, a frame it one enC of s i; c: ble, means mounte i on s if. fr..me for tightening and holding s id 0; ble taut, a cable connected with said c; .rrier for moving the same on said supporting-cable, me. ns mounted in connection with said frame for moving said carriermoving cable, and means for simultaneously actuating the means for tightening the supportingcable and the means for moving the carriercable.

4. In a conveying apparatus, a supportingcable, a carrier movable on said cable, a frame at one end of said cable, a drum on said frame for tightening and holding said cable taut, releasable means for preventing the backward movement of said drum, a gear connected with said drum, a cable connected with the carrier for moving the same, a drum on said frame for operating said'carrier-cable, a driving-shaft for operating said carrier-cable drum, a pinion on said driving-shaft engaging the gear on said supporting-cable drum for actuating the same, and a clutch on the driving-shaft operating in connection with said pinion, whereby the supporting-cable may be tightened when desired and during the operation of the carrier-cable drum.

In witness whereof we have hereunto affixed our signatures in the presence of the witnesses herein named.
